POCSAG FORMAT Programmable data transmitter & receiver

8 Dry-Contact Inputs POCSAG Transmitter

SKD 838 (Semi-Kit Device)

The well-designed miniature Model M-838SKD, which has the 8 dry-contact inputs POCSAG Encoder with 10mW or 35mW built-in FSK Transmitter, is an USB microprocessor control product mainly used for message encoding in the POCSAG paging format. The 8 inputs of the M-838SKD allows the device to generate 8 different addresses and numeric or alphanumeric messages and control codes for operation of the Y1734 POCSAG receiver.
